Abstract
Abstract A photographic camera which utilizes magazines provided with markers indicating the sensitivity of film therein. The marker of a magazine which is inserted into the camera is scanned by a scanning member which is coupled to the door-locking device of the camera by a looped snapover spring. When the locking device is moved by hand to an inoperative position in which the user can open the door to gain access to the magazine in a camera housing, the spring biases the scanning member to a predetermined starting position. When the door is closed and the user moves the locking member toward operative position, the spring snaps over and shifts the scanning member into engagement with the marker of the inserted magazine. The spring then biases the scanning member against the marker and simultaneously opposes movement of the locking member from operative position.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
127 words
In a photographic apparatus for use with film magazines of the type having encoded information to condition the exposure control as a function of the sensitivity of film, a combination comprising scanning means movable between a first position and a plurality of second positions each of which is indicative of a different film sensitivity; actuating means movable by hand between a first end position and a second end position; and coupling means for traNsmitting motion from said actuating means to said scanning means, said coupling means comprising a snapover spring arranged respectively to bias said scanning means to first and second positions in the first and second end positions of said actuating means and to oppose the movement of said actuating means from both end positions thereof.
Claim 2
Dependent Claim
127 words
In a photographic apparatus for use with film magazines of the type having encoded information to condition the exposure control as a function of the sensitivity of film, a combination comprising scanning means movable between a first position and a plurality of second positions each of which is indicative of a different film sensitivity; actuating means movable by hand between a first end position and a second end position; and coupling means for traNsmitting motion from said actuating means to said scanning means, said coupling means comprising a snapover spring arranged respectively to bias said scanning means to first and second positions in the first and second end positions of said actuating means and to oppose the movement of said actuating means from both end positions thereof.
Claim 3
Dependent Claim
31 words
A combination as defined in claim 1, wherein said spring comprises a loop having a first end connected with said scanning means and a second end connected with said actuating means.
Claim 4
Dependent Claim
27 words
A combination as defined in claim 1, further comprising a housing having guide means for confining said actuating means to reciprocatory movement between said end positions thereof.
Claim 5
Dependent Claim
31 words
A combinations as defined in claim 1, further comprising a housing having guide means for confining said scanning means to reciprocatory movement between said first position and said second positions thereof.
Claim 6
Dependent Claim
66 words
A combination as defined in claim 1, wherein said actuating means comprises a locking member and a knob connected with said locking member, and further comprising a door movable between open and closed positions, said locking member being arranged to respectively permit and prevent opening of said door in closed position of the door when said actuating means respectively assumes said first and second end positions.
Claim 7
Dependent Claim
37 words
A combination as defined in claim 1, wherein said scanning means comprises a reciprocable carrier and a tongue on said carrier, said tongue extending into a notch provided in a magazine which is inserted into the camera.
Claim 8
Dependent Claim
37 words
A combination as defined in claim 1, wherein the distance between the first and second end positions of said actuating means exceeds the maximum distance between the first position and a second position of said scanning means.
Claim 9
Dependent Claim
62 words
A combination as defined in claim 1, wherein said scanning means includes a filter having zones of different light transmissivity and further comprising a photosensitive receiver located behind said filter, said scanning means being arranged to maintain in the first position thereof said filter in a position in which the zone of maximum light transmissivity is located in front of said receiver.
Claim 10
Dependent Claim
21 words
A combination as defined in claim 1, further comprising means for arresting said actuating means in each of said end positions.
